Monterey Herald, Nov 3, 2015 (emphasis added): Local whale watching tour companies and conservationists claim the anchovy population has “collapsed” due to environmental reasons… Fishing groups disagree, though they note the bay has seen some dramatic environmental changes.

Santa Cruz Sentinel, Oct 30, 2015: Monterey Bay anchovy numbers in decline, groups say… “Since late September, the whale numbers have decreased, their behavior has changed and their food, anchovies, are less abundant,” said Nancy Black, marine biologist… Whale watching tour companies and conservationists claim the anchovy population has “collapsed” due to environmental reasons… The fishing industry says that’s not the case though ocean conditions have been unusual. Some scientists, however, are finding a drastic decline in the forage fish… [Pacific Fishery Management Council staff officer Mike Burner said,] “The council’s definitely concerned with some of the things they’ve heard.”… “The population has truly collapsed,” [said] William Sydeman, president and senior scientist at the Farallon Institute. “There’s no way fishing could have that kind of impact, so it had to be environmental.”… plankton populations are low, affecting their predators up the marine food chain… “When anchovy numbers are low, they crowd at the coast and appear to be abundant,” Sydeman said… At the same time, the lack of anchovies offshore are maybe in part why scores of sea lions and sea birds… are starving up and down the coast. “Right now we’re seeing that the whales are more scattered and seem to be looking harder for food,” said Dorris Welch, marine biologist…

Monterey Herald, Oct 19, 2015: Plenty of anchovies in Monterey Bay, but maybe not elsewhere… Market squid are disappearing, and in their place, fishing boats are reeling in piles of anchovies. But while they appear abundant, conservation groups warn that the forage fish may be at their lowest levels since the 1950s. “It’s an anomalous year,” said Diane Pleschner-Steele, executive director of the California Wetfish Producers Association. [Oceana’s Geoff Shester said,] “new information shows that the stock is at such a low level right now, it’s literally in a state of collapse.” Survey cruises conducted by the Southwest Fisheries Science Center detected little to no anchovy eggs from 2010 to 2013… Sit on the docks where anchovies are sorted and you’ll likely see lots of the silvery fish piling up. But it’s a mirage, warns William Sydeman, ecologist of the Farallon Institute, who coauthored the paper that estimated anchovies at low levels. “People think that if they’re in Monterey Bay, they must be everywhere,” Sydeman said. “They’re not. They’re only in Monterey Bay.” Sydeman said anchovies tend to aggregate near shore when their numbers are low…

KION, Oct 21, 2015: California’s last anchovies crowd in the Monterey Bay; Researchers say a massive decline of the fish is throwing off the ecosystem — Several conservation groups and whale watching operators are very concerned about the anchovies in the Monterey Bay… Recently, fishermen have been hauling out 120 tons of anchovies every night, but those anchovies are some of the last along California’s coast… “The anchovy abundance out here, and off the entire state, has gotten to some of the lowest we’ve seen since the 1950s,” [Oceana’s Geoff Shester] said. “Scientists are calling it an actual collapse.”… Anchovies are an important part of the ecosystem. That’s why these groups say if nothing is done, there could be long-term impacts. “We’re really worried that right now we are seeing major die-offs of sea lion pups and pelicans because they’re starving and not able to reproduce,” Shester said. “And that’s because there’s not enough sardines and anchovies out there.” “We’ve noticed the numbers of whales have dropped significantly,” [marine biologist Nancy Black] said.
